The Isolation of Condensed Aromatics from a High-temperature Coal Tar
A high-temperature coal tar collected from Xuzhou Coking Plant, Saint-Gobain Pipelines (Xuzhou) Co., Ltd. was exhaustively extracted with petroleum ether (PE). The extract was sequentially eluted with PE and PE/carbon disulfide mixed solvent with PE volume contents of 90, 80, 60, 50, and 40% to afford eluates 1 to 6 (E-1 to E-6), respectively. The eluates were analyzed with gas chromatography/mass spectrometer. In total, 12 condensed arenes with 3 to 6 rings and 14 heteroatomic condensed aromatics with 2 to 4 rings were detected in E-4 to E-6.
